Refactor Suggestion Controller.rb

Line 76 and 77: use more Ruby-like String concepts

Use Ruby-like string concepts .empty? to replace == " " expression.

Change from:

flash[:success] = 'Thank you for your suggestion!' if @suggestion.unityID != '' "
flash[:success] = 'You have submitted an anonymous suggestion. It will not show in the suggested topic table below.' if @suggestion.unityID == '' "

to:

flash[:success] = 'Thank you for your suggestion!' unless @suggestion.unityID.empty?
flash[:success] = 'You have submitted an anonymous suggestion. It will not show in the suggested topic table below.' if @suggestion.unityID.empty?

Line 94: Refactor create_new_team to assignment_team.rb

Move create_new_team function from suggestion controller.rb to assignment_team.rb.

Line 160: Refactor approve_suggestion to indicate that notification is being sent

Originally, there is an error when the instructor approves a topic:

To fix it, we added new_topic_from_suggestion to app/models/sign_up_topic.rb and used it in approve function of app/controllers/suggestion_controller.rb.

def self.new_topic_from_suggestion(suggestion)
     signuptopic = SignUpTopic.new
     signuptopic.topic_identifier = 'S' + Suggestion.where("assignment_id = ? and id <= ?", suggestion.assignment_id, suggestion.id).size.to_s
     signuptopic.topic_name = suggestion.title
     signuptopic.assignment_id = suggestion.assignment_id
     signuptopic.max_choosers = 1
     #return this model based on these checks
     if signuptopic.save && suggestion.update_attribute('status', 'Approved')
       return signuptopic
     else
       return 'failed'
     end
 end

Then the approving bug is fixed:

Test by RSpec

Test the submit, student_view, student_edit, update_suggestion, add_comment function

• Test student_view

  describe '#student_view' do
    it 'renders suggestions#student_view' do
       get :student_view, id: 1
       expect(response).to render_template(:student_view)
     end
  end

• Test student_edit

  describe '#student_edit' do
      it 'renders suggestions#student_edit' do
        get :student_edit, id: 1
        expect(response).to render_template(:student_edit)
      end
  end
